Setting Shadow ROM Options
Your computer can access RAM faster than ROM. Two options,
Shadow BIOS
ROM and
Shadow Video ROM, allow your
system to copy the contents of its system and/or video ROM
into RAM
(WP-Shadow)
or external cache, if you have some
installed
(Cacheable).
When you use shadowing or the
external cache, your system can perform certain operations
faster. You cannot enable
Memory
Remapping
when you
enablethe Shadow Video ROM and the Shadow BIOS ROM
options.
Remapping Memory
The Memory
Remapping
option allows you to relocate 384KB
of memory to the top addresses of DRAM. You must disable
this option if you have enabled both the shadow Video ROM
and the
Shadow BIOS ROM
options or any of the
Shadow
